Primary Hues
Grey-Green, Dark Grey, Black with flashes of blue, green, yellow, red, purple (labradorescence)
Geological & Scientific Details
Labradorite is classified as a tectosilicate minerals, feldspar group, plagioclase series mineral which typically crystallizes in the triclinic system. Its chemical formula is (Ca,Na)(Al,Si)4O8, where Na is 30-50% & Ca is 50–70%. Common crystal habits include crystals typically thin and tabular, rhombic in cross section, striated; massive.
